Kennametal 3381144 Ksem Carbide Replaceable Tip Drill 47/64

Product Description

The KENNAMETAL 3381144 is a carbide replaceable tip drill in the KSEM series, designed for precision hole-making in demanding metalworking applications. It accepts the KSEM0734HPL insert tip, which features a solid carbide construction with an AlTiN (aluminum titanium nitride) PVD coating and HPL insert geometry. The 140-degree included angle point is suited for clean entry and exit in a variety of workpiece materials. The insert is held by a clamp mechanism and fits an insert seat size 2 body. This part is typically procured and installed by machinists and tooling specialists on CNC drilling and machining centers.

This drill tip is engineered for use across a broad range of primary workpiece materials, including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It is rated under ISO material grades P, M, K, N, and S, making it a versatile option for production shops running mixed-material operations. The KSEM series is commonly used in applications involving inclined exit drilling, stacked plate drilling, and standard through-hole operations. The helical, regular spiral flute design with a 2-flute, 2-margin configuration supports chip evacuation in these conditions.

Key Features

• Solid carbide tip with AlTiN PVD coating for wear resistance in steel, stainless, and superalloy materials
• 140-degree included angle for controlled entry and reduced thrust force
• HPL insert geometry with 2-flute, 2-margin configuration for chip control
• Clamp-style insert holding method for repeatable tip seating and replacement
• Compatible with inclined exit and stacked plate drilling applications
• KSEM series insert seat size 2 for use with matching KSEM drill bodies

Compatibility

Designed for use with KSEM series replaceable tip drill bodies accepting insert seat size 2. The ISO designation for this insert tip is KSEM0734HPL. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium per ISO material grades P, M, K, N, and S.

Installation Notes

Installation and replacement of carbide drill tips should be performed by a qualified machinist with the machine fully powered down and the spindle locked. Use the manufacturer-specified torque wrench or hex key for the clamp screw to ensure proper tip seating — do not over-tighten by hand. Inspect the insert seat for debris or damage before installing a new tip. Follow applicable shop safety procedures and machine tool manufacturer guidelines during tooling changes.
